A sensor 5 such as an infra-red rays sensor for sensing a position 10 where contaminant is produced is arranged at ceiling surface 7, both fan 8 and a diffuser 1 are controlled by an output signal for sensing the contaminant and then a controller device 6 for adjusting an amount of air and an air direction of the diffuser 1 is provided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air cleaning system that purifies contaminated air with high efficiency.

[Conventional technology]

As a conventional air cleaning system, there is one shown in FIG.

In this conventional air cleaning system, in a closed space, an air outlet [1] is provided on each of two opposing end surfaces of a ceiling surface @, and most of the ceiling surface @ is an inlet (2).

Further, the above-mentioned air outlet (■) and suction opening (2) are connected by a duct (2) at the back of the ceiling. Inside the duct ■,
It has a fan and a filter [4] that collects pollutants such as cigarette smoke, and an air outlet that faces a sensor such as infrared rays that detects the location [phase] of pollutants such as cigarette smoke. It has a configuration including a control system [6] such as an inverter that controls the amount of air from the inverter. In this way, by controlling the amount of air from each of the opposing air outlets 2, the upward airflow [phase] lifts the pollutants to the location where the pollutants are generated, as shown by the arrow in Figure 3. After removing the purified air with the filter ■ inside the duct ■, the purified air is returned to the room through the outlet ■.

[Issues that sales aim to solve]

In conventional air purification systems, the air outlet
If only the air volume from Since a large amount of air is required and a fan with a large capacity is required, there are problems in that equipment costs, equipment space, etc. become large.

An object of the present invention is to enable not only the air volume but also the wind direction to be adjusted, thereby achieving more efficient air purification with a smaller air volume.

[Means to solve the problem]

The gist of the present invention is that the suction port [2
], three or more air outlets [1] are provided in positions surrounding the air inlet [2], and the air inlet [2] and the air outlet [1] are connected by a duct ■, and the air outlet [1] is connected to the air outlet [1] in the duct ■. is equipped with a fan for blowing air and a filter [4] for collecting pollutants, and a sensor [5] such as infrared rays that detects the position [phase] of pollutants such as cigarette smoke.
This air cleaning system is characterized by having a control device [6] that adjusts the air volume and direction of the blow-out based on the detection signal.

That is, in order to achieve the above object, in the air purification system of the present invention, a suction port [2] is provided on the ceiling surface (■), and three or more holes are provided on the ceiling surface (■) at positions surrounding the suction port [2]. Provide an air outlet [1]. and a sensor [6] that detects the location [phase] of pollutants such as cigarette smoke.
], and is equipped with a control system (2) that adjusts the air volume and direction of each outlet (2) based on the output signal.

A control system that adjusts the wind direction is a control system that creates an updraft at the position [phase] where pollutants are generated, and the air outlet so that the contaminated air rides the updraft and is carried to the inlet without dispersing. The direction of the pollutant generation position [
This is to adjust the air to be blown toward the front.

[For production]

When the sensor ■ detects the location [phase] of pollutant generation, the control system ■ will operate three or more air outlets.
From there, air is blown in front of the generation position [phase] to create an upward airflow [6] that joins above the generation position [phase]. In this way, air is blown spot-wise to the pollutant generation position (phase), so air is purified efficiently and large-capacity equipment is not required.

Note that as long as there are three or more outlet ports (2) around the inlet (2), the number of outlet ports (2) is arbitrary, and a spot-like upward air current can be created at the pollutant generation position (phase).

〔Example〕

An example will be explained using FIG. 1 and FIG. 2.

In a room ■ that is normally used in a closed state, a suction port [2] consisting of many small holes is installed in the center of the ceiling surface ■.
Air outlets [1] are provided at the four corners of the ceiling surface ■. The air outlet ■ and suction port ■ are installed in the duct ■ in the ceiling.
The duct is connected with a fan for blowing air.
A filter [4] that collects very fine particulate pollutants such as cigarette smoke is arranged, and a sensor [6] such as infrared rays that detects the position [phase] of pollutant generation is arranged on the ceiling surface ■.
The configuration includes a control device (2) that controls the fan (2) and the air outlet [1] to adjust the air volume and direction of the air outlet (2) based on the output signal of the pollutant detection.

When the pollutant generation position [phase] is on the desk O, the direction of the air blown from the air outlet ■ is aimed at the corner located at the shortest distance among the four corners of the desk 0. The blown airflow bounces off the desk ■, creating a spot-like upward airflow [6] above the pollutant generation position [phase], sending the pollutants to the suction port ■, and passing through each duct ■, ■
After passing through , ■, [Yes] and purifying with a filter ■,
The circulation of air being sent out from the air outlet ■ is repeated again.

〔Effect of the invention〕

As described above, according to the air cleaning system of the present invention, it is possible to generate an upward airflow toward the ceiling surface at a pollutant generating position in a spot-like manner and with a smaller air volume than the conventional system.
